Which command copies all files that start with 'chap' followed by exactly two characters into the progs directory?
Explanation
Option A uses 'chap??' which matches filenames beginning with 'chap' followed by exactly two characters, making it the correct command to copy those files into the progs directory. Option B copies files starting with 'chap' and any number of characters, which is broader than required. Option C incorrectly uses character classes and paths. Option D copies files named 'chap??' into a different directory path, which is not the intended destination.
